User-specified password displaying during install

Description

I appreciate the improvement that users are prompted to choose their own password. However I think there has been an oversight with this change.
Historically it has been essential to display the password onscreen, because the user did not specify it.

I believe it is now dangerous to continue displaying a user's own specified password. It is obscurred with an <input type="password" /> field, so one would not expect it to be visible on a subsequent page.
Many people use their passwords for several different sites; to display this password on screen, when it was originally obscured is likely to upset people who weren't expecting this behaviour.

If we decide to not show the password on the subsequent screen, we will have to add a "Type password again" field to the original screen, otherwise the user might accidentally make a typo and does not really know about.
